| Abstract(in English) | We previously reported that teraherts(THz) radiation can emit from YBCO thin films irradiation with femto second laser pulses and explained its mechanism as an ultrafast supercurrent modulation. We proposed and demonstrated a new method to obtain two dimensional supercurrent distribution i YBCO thin film. The distribution images of the transport and persisting currents were obtained and their characteristics were qualitatived explained by the Bean model. This result revealed that the supercurrent distribution imaging system can be constructed based on the THz emission-detection system. |
